Hi i am 16 years old and about 2 months ago i stupidly had unprotected sex with a girl. I asked her after if she had hiv and she said "no dont be silly" that was it really. But recently i have been experiencing symptoms such as 2 mouth ulcers , oralthrush , my skin feels quite hot , swollen lymph nodes in neck and groin and also having loads of bowel movement. Could this be hiv? I went to the clinic and got tested for chlamydia and gonorrhoea. Chlamydia came back positive but gonorrhoea negative. It was only a one time thing and i have not spoke to the girl since. Could these symptoms be due to stress from my exams i just took? Please help me.
